@JeffreyLin there's like maybe 20 major ad networks, how do you end up with 23k..?

Or does it add all the unique hash subdomains and shit too?

@JeffreyLin No. A few million might. Your browser doesn't care, it just does an nslookup, which your system C library handles through order of precedence of resolvers (where hosts comes first). It might slow down resolution by a fraction of a second, but 23k lines is chump change to parse.

@TimPost assuming it does anything other than a linear search

I have to now pretty much always have my email off/closed because I get about a hundred emails an hour 95% of which are spam and the others are ads I kinda care about (like humble bundle notifications)

@Ieuan it'd have to, I don't think hosts files allow wildcards

@KevinvanderVelden But at that point why not just block all requests to the IP of the main domain

I'm using adfreetime.com to watch the US netflix and that has a built-in adblocker which pretty much gives me 0 slowdown and works great

It doesn't block all ads on the internet and it has some issues too but for just the ads it's aimed at it works perfectly and isn't noticable

@ratchetfreak It does a linear search. It's cached, just like any other file by the kernel, so it's pretty fast.

Well, by Linux anyway.
